Application May 17, 1943, Serial No. 487,203

2 Claims.

The main objects of this invention are:

First, to provide an improved lamp including a lamp shade holder whichis highly efficient in supporting the lamp shade in proper` relation tothe lamp.

Second, to provide a lamp shade which is capable of adaptation to lampsof the upright socket type as well as to lamps of the inverted sockettype.

Third, to provide a lamp shade holder which may be applied to a lampsocket of standard types in a very secure and eective manner for propersupporting of the shade.

Fourth, to provide a structure having these advantages which may beeconomically formed of re resistant fibrous material and which is veryattractive in appearance.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

'Preferred embodiments of the invention are illustrated in theaccompanying drawing, in which:

Fig. 1 is a fragmentary side elevation of a lamp embodying the featuresof my invention, the shade and holder being shown partially broken awayand partially in vertical section.

Fig. 2 is a plan View of a desirable design of one of the shade holders.

Fig. 3 is an enlarged fragmentary vertical section showing certain ofthe structural details.

' Fig. 4 is a fragmentary view illustrating the adaptation of my shadeand shade holder to a lamp having an inverted socket.

Fig. 5 is a fragmentary View of a modied form of shade structure.

In the embodiment of my invention illustrated, I represents the lampstandard, 2 the upright socket, and 3 the lamp bulb threaded into thesocket.

The lamp socket is formed with external threads 4, these commonlyresulting from the forming of the internal threads to receive the lamp.

The skirt or wall portion 5 of the shade may be of parchment or othersuitable material and the structure shown is conical and provided withtrimming 6 at the top and bottom. This of course is optional and thewall may be provided with any suitable design.

The lamp shade holder designated generally by the numeral 1 is formed ofa brous, preferably nre-resisting, material, the product commerciallyknown as Masonite being an example of a material which I have foundsatisfactory. This disk is died or stamped out to provide an annular rimportion 8, a central hub portion S with connecting spider portions IIJ.The hub portion has a central opening II therein adapted to receivethe'socket 2.

The holder is of substantial thickness and the opening II is of suchdiameter that the holder may be arranged on the socket and rotatablyforced downwardly thereon with a result that the threads of the socketform threads in the holder and a very secure engagement is provided andone which prevents accidental disengagement of the holder and alsotilting of the holder on the socket.

The lamp shade walls are preferably provided with a supporting member I2at the top thereof which is adhesively secured as indicated at I3 withinthe shade wall adjacent the top thereof. This may consist merely of anannular ring I1 as shown in Fig. 5 or it may be provided with the hubportion I5 as shown in Fig. 1 having a central opening I6 thereincorresponding to the opening I I in the shade holder 'I so that thisupper member I2 may be secured upon the threaded socket of an invertedlamp in the same manner as described for the holder 'I and as isillustrated in Fig. 4. In that case, the holder 'l would not be used andthis holder is not secured within the lamp shade. It is adapted for useon shades varying somewhat in size and shape and effectively holds themagainst tilting or canting on the holder. A further advantage is thatthe shades and their holders may be shipped or packed in the knockdownor separated in which condition the shades may be nested.

My lamp shade and shade holders may be formed without the use ofmetals-that is, entirely formed of fibrous material, may be veryeconomically produced, and at the same time are highly ecient for thepurpose, and attractive in appearance.

I have illustrated certain practical commercial embodiments of myinvention but have not illustrated other adaptations or embodimentswhich I contemplate, as it is believed that this disclosure will enablethose skilled in the art to embody or adapt my invention as may bedesired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a lamp, the combination with a lamp standard provided with anexternally threaded lamp socket, of a lamp shade holder formed of a diskof re resistant fibrous material of substantial thickness and comprisingan annular rim portion, a central hub portion having an opening therein,and a spider portion, said opening being adapted to receive said socketand to be rotatably engaged with the threads thereof, and a shadesleeved over said holder, said shade being provided with an annularreinforcing member of re resistant fibrous material fitted Within andadhesively secured thereto adjacent its upper end, said shade beingseparate from said disk and of frustrum shape to permit a plurality ofshades being packed in nested relation separate from the disks forshipping and to permit a shade to Wedgingly engage a disk when the lampis assembled, said shade being of the greatest diameter at the lower endthereof, said disk supportingly engaging the shade adjacent the lowerlarger end thereof.

2. In a lamp, the combination with a lamp standard provided with a lampsocket, of a lamp shade holder formed of a disk of iire resistantfibrous material and comprising a rim portion, a central hub portionhaving an opening therein, and a spider portion, said opening beingadapted to receive said socket, and a shade embracing said holder, saidshade being provided with an annular reinforcing member of re resistantfibrous material tted within and adhesively secured thereto adjacent itsupper end, said shade being of progressively increasing diameter fromthe upper to the lower end thereof, said shade holder supportinglyengaging the shade in the lower larger end thereof.
